You do have a plug for the electrical connection on your tv, don't you? You will need mirrors, unless your tv is pretty wide. The mirrors on my Mountaineer aren't really out far enough to really let me see behind the 181. I got some cheap strap-on ones, and they seem to do the job.
We bought a longer sewer hose yesterday at the RV show because we're going to the Heartland Rally in June and we were told that all hookups are at the rear of the campsites. I may need to get a longer water hose, or maybe not. It may be close, so I'll probably go ahead and get one just to be safe.
